The best, if you choose to stay within the AMD group, will be the RX 480 within the one you mentionned. For me, tha allstar card is the RX 470.

-If you have free or very low cost electricity: buy Gigabyte R9 390 x5.

-If you have expensive electricity: buy Asus Radeon RX 480 x5.

You won't receive many or good answers with a question like that...

Of course you can mine with every GPU, but it depends what you want to do, one hobby rig, to build a mining farm in near future, do you pay for electricity or not?
First compare the prices of the GPU's, After that check how many MH/s you will receive of every rig. After that find information about the power consumption of the cards and do the math.

I can write a lot more information but first make a little research and ask again.

Everyone could help here, but the general rule in these situations when presented with someone who, with information all around, asks a question that shows no effort on their part is frankly to ignore it.

where to buy this asset?

I don't want do any FUD, but you know  altcoin market is very dangerous sometimes, many newbiers come in and....
yes this is very impressive price grew

But take a look at the rich list of This coin and look also the hash rate....



Hashrate very low and 89% of coin in 1 address....

Trade with attention

Denied



This will be final week of campaign, Site owner not getting his desired results

It's water under the bridge at this point, but having an exit in mind if things go south would be good on the next trade.

Don't fight a trend, best to cut losses and move on, there will always be another trade -- if you manage to limit your losses.

this may be the poorest communication I've seen from a team in a long time. will be a disaster for anyone still holding; i got out weeks ago and was waiting to buy back...ain't gonna happen now.

hope is a bad investment strategy

lets see how much its going to be cooked.
